PROBLEM TO BE SOLVED: To have more efficient vibration-reducing control over an active type engine mount which intervenes between a power unit and a car body. SOLUTION: As a result of the establishment of vibration transmission path which does not pass through an active type engine mount 1, under the circumstances where a possibility cannot be decreased that a bending vibration mode of a body skelton is excited only by reducing the vibration which passes through the active type engine mount 1, the active type engine mount 1 is controlled in accordance with a residual vibration signal eA which is an output of an acceleration sensor 27 so that the engine mount 1 functions as an actuator of an active vibration absorbing device. On the other hand, as a result of the failure in the establishment of a vibration transmission path which does not pass through the active type engine mount 1, under the circumstances where the vibration level on the side of a car body 35 can be reduced by reducing the vibration which passes through the active engine mount 1, the active type engine mount 1 is controlled in accordance with the residual vibration signal eL which is an output of the built-in load sensor so as to reduce the vibration just under the engine mount 1. |
